[NSRCA-discussion] Interference Problem

[Ken Thompson]

Hey Scott,

If you want an easy way to operate your servos, one at a time, slowly as suggested, come and get my Hitec programmer.  Just plug the servo in and you can move the dial both directions, to operate the pot, to see if the buzzing stops.  Give me a call if you need it, I'll be around most of the day today and tomorrow.

Ken

  Jay,

  They are all JR Digis. I would think that mine would not buzz with no linkage, but they buzz profusely. The only one that doesnt is the new elevator servo I just installed :-)

  Hopefully this along with other servos will solve the problem. 

  Thanks guys!

  Scott

    At this point keep on eliminating and unplug things until the problem goes away. You changed the batt rec and trans. now change the switch assembly and harness.You said a change in attitude which might indicate elevator servo. Replace it also. You are on the right track.If these are hi-dollar servos and have a lot of time on them, they can be rebuilt,send them off for feedback pots and gears.

    Hopefully someone can help with this. I have been getting interference on my Focus for the past three flights causing me to land, and I can't seem to solve the problem. Initially I thought it was the RX and TX, so I changed them both and moved to an entirely different frequency. I flew the plane again and it glitched in the air just as the first two times. The glitch is a quick and significant change in attitude. When I landed, the regulator was warm so I removed it thinking it was going bad. I replaced it with a regular 4 cell NiCd pack. I changed the receiver once again and am still getting the glitch. I decided to remove all the arms from my servos (JR Digitals) so that there would be no load and see how the problem is. The servos, under no load, buzz considerably. It's not the "I'm under load" type buzz, but more of a twitching, crackling type buzz. Are my servos going bad? When I plugged in a new 8417, the buzz is non existant in that servo. 

    Any help would be appreciated!!

    Scott
